FILLING-FORK FOR LOOIVIS- SPECIFICATION forming part of Letters PatentNo. 779,966, dated January 10, 1905. Application filed July 23,1904Serial No. 217,834..

T 0 all whom, it may concern:

Be it known that I, RICHARD RILEY, a citizen of the United States, and aresident of Fall River, county of Bristol, State of Massachusetts, haveinvented an Improvement in Filling-Forks for Looms, of which thefollowing description, in connection With the accompanying drawings, isa specification, like characters on the drawings representing likeparts.

This invention has for its object the production of a novel filling-forkfor looms so constructed and arranged that the ends of the tines aregreatly strengthened and braced against any tendency to bend.

- If the tines of a filling-fork become bent out of place, seriousdifliculty arises, for the bent tine or tines may engage the grid andcause the fork to be tilted, even if the filling is absent, and a thinplace is made in the cloth. On the other hand, the bend may be such thatwhen the filling is present it cannot act to tilt the fork, and then thenormal operation of the loom is changed, as by stoppage or a change offilling in an automatic loom when such change is wholl y uncalled for.

In the present embodiment of my invention I have united the lower endsof the fork-tines in such a manner that they are braced and strengthenedwith greatly-decreased liability to bend and more weight is added nearthe free ends of the tines without interfering with the normal operationof the fork. On certain weaving, especially with the coarser numbers ofyarn, this additional weight at or near the ends of the tines isdesirable.

The novel features of my invention willbe fully described in thesubjoined specification, and particularly pointed out in the followingclaim.

Figure 1 is a cross-sectional view of a portion of a loom, showing thegrid on the lay, the fork-slide, and a filling-fork carried therebyembodying one form of my invention; and Fig. 2 is an enlargedperspective view of my novel filling-fork detached Referring to Fig. 1,the lay A having a grid Gr thereon, the breast-beam A having a stand orguide f rigidly secured thereon, the fork-slide f' mounted thereon, andthe weft-hammer W may be and are all of usual or well-known constructionand operate in a manner familiar to those skilled in the art.

The filling-fork embodying my present invention is clearly shown in Fig.2 and, as herein illustrated, comprises a two-part body 1 2, having arigidly-attached loop or tail 3 to cooperate with the usual hook of thewefthammer W, the member 2 of the body having a transverse hole 4 forthe pivot or fulcrum pin 22 Fig. 1. The upper ends of the tines 5 arerigidly secured in any suitable manner to the body, said tines dependingtherefrom, and at their lower ends they are bent backward or toward thefront of the loom when the filling-fork is in place, as at 6. Theextremities of the bent portions 6 are rigidly united or connected by alateral connection 7, and herein this is shown as an integral part ofthe two outermost tines, the end of the central tine being unitedthereto at 8 by brazing, soldering, or in any other suitable manner.

When the lay beats up, the bent lower por- I tions 6 sweep across thelay in the usual transverse recess formed in its raceway and the forkcooperatesin usual manner with and is tilted by the filling. If thefilling is absent, the tines can pass between the bars of the grid G,Fig. 1, as is customary, the bent portions 6 being ofsufficient lengthto prevent any engagement of the connection 7 with the grid. Thisconnection 7 acts as a lateral brace to stiffen and strengthen the lowerends of the tines, preserving them in parallelism and obviating anytendency thereof to'become bent out of their proper positions.

I prefer to slightly upturn the bent portions 6 of the tines, as shownbest in Fig. 1, so that they will sweep easily across the bottom of therecess in the raceway of the lay.

Having fully described my invention, what I claim as new, and desire tosecure by Letters In testimony whereof I have signed my name Patent,isto this specification in the presence of two sub- I As a new articleof manufacture, a fillingscribing Witnesses.
